Title: The Innovations of Takashi Nomiyama
Introduction
Takashi Nomiyama is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of engineering, particularly in the development of positioners. With a total of nine patents to his name, Nomiyama's work has had a considerable impact on various industries.
Latest Patents
One of his latest patents involves a positioner that includes an electro-pneumatic converter. This converter transforms an input electric signal into a pneumatic signal, which controls the valve opening of a regulating valve. The operational unit is driven according to the pneumatic signal. Additionally, the invention features an operating-point searching unit that modifies the electric signal through open loop control to find an operating point that indicates a target valve-opening value. This occurs when the output air pressure of the pneumatic signal begins to change. Furthermore, the positioner executes a PST on the regulating valve using the operating point identified by the searching unit. The operating point is set based on the electric signal value when the output air pressure aligns with a first reference value.
Another patent describes a positioner where a driving signal is set to its minimum and maximum values. The valve opening positions are stored after the valve has settled, and the time series position information is recorded. This information allows for the calculation of the time required for the valve to move between two prescribed opening positions, establishing a first response time.
